Ep 41: Dolphins and Sargassum with Dr. Denise Herzing and Cassie Rusche

The Sargassum Podcast

Dr. Denise Herzing is the Founder and Research Director of the Wild Dolphin Project and has studied Atlantic spotted dolphins in the Bahamian waters for over 35 years. In addition to many scientific articles, she is the co-editor of Dolphin Communication and Cognition, author of “Dolphin Diaries: My 25 years with Spotted Dolphins in the Bahamas” and “The Wild Dolphin Project (2002)”.

Cassie Rusche spends her summers living on a boat in the Bahamas studying wild dolphins. But 10 years ago, she thought she’d be working as a pharmacist. She started University as a pre-pharmacy student. However, after just a few short months of school and working in a pharmacy, she realized it was not for her. Eventually she discovered her real passion for understanding animal behavior. So, she switched to the ecology/evolution/organismal biology concentration and has been working for the Wild Dolphin Project since her graduation.

Wild Dolphin Project is the world’s longest running underwater study of dolphins in the world. Since 1985, the team has spent months out at sea every summer, living on boats and studying two species of dolphins that live on the shallow sandbanks of the Bahamas: Atlantic spotted dolphins and Atlantic bottlenose dolphins. Researchers have made many discoveries over the years regarding aspects of social structure, paternity, habitat use, behavior, communication, and movement patterns.
